To all whom it may concern:

Be it known that I, OLIVER H. ROBERTSON, a citizen of the United States, and a resident of Forestville, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Stanchions, of which the following is a specification.

My invention relates to the class of devices employed for securing cattle in a stall; and the object of my invention is to provide a de vice of this kind that shall be extremely cheap to manufacture, strong and durable in use, and of great convenience in operation. A device in the use of which these objects may be attained is illustrated in the accompanying drawings, in which- Figure 1 is a top View of my improved structure. Fig. 2 is a view in elevation, on reduced scale, of the device with parts broken away. Fig. 3 is a view in lengthwise section of the end of a neck-bar. Fig. 4 is a view in elevation,.looking from the left of Fig. 1, with the movable neck-bar removed. Fig. 5 illustrates one of the connections of neck and cross bar. Fig. 6 is a View of the upper end of the pivoted neck-bar. Fig. 7 is a plan view of the adjustable neck-bar connection with parts broken away to show construction.

In the accompanying drawings the numeral 1 indicates the top cross-bar, and 2 the bottom cross-bar. These bars are constructed of strips of metal, preferably iron, bent to form two side parts 3 and 4, as clearly shown in Fig. 1 of the drawings.

A rigid neck-bar 5 is secured at each end to the cross-bars and has a reduced portion 6 on its end fitting between the side parts of the cross-bar (see Fig. 3) or cuts 7, within which the sides of the cross-bar may fit. (See Fig. 5.) The bend in the cross-bar is formed beyond the edge of the neck-bar, and a U-shaped bolt 8 extends transversely through the neckbar and upward along the edges thereof through the opening between the side parts of the cross-bar and through a plate 9, being secured as by means of nuts. This plate 9 has flanges 1O closely fitting the sides of the neck-bar, and the under surface of the plate may be serrated, as shown in Fig. 2 of the drawings, this serrated surface fitting serrations on the upper edge of the side parts of the cross-bar, thus holding the plate firmly iggainst movement lengthwise of the cross- The sides of the upper cross-bar flare outwardl y at one end, providinga bifurcated opening or mouth 11, the bifurcated ends of which lie on opposite sides of the end of the pivoted neck-bar 12, when the parts are in place. This neck-bar 12 is pivoted to the lower cross-bar, as shown in Fig. 2 of the drawings.

Both the upper cross-bar and the lower cross bar are preferably formed of metal strips, which embrace the neck-bars on either side either as to the whole of said bars, as indicated in Fig. 3, or by being cut into the bars and embracing a portion thereof, as indicated in Figs. 1 and 5. In either case the cross-bars are what might be termed crossbars having side parts, which side parts have lying between them when in position the neckbars, to which they are secured in the manner described.

Within the mouth 11, formed in the side parts of the upper cross-bar, a latch-plate having a cam-plate 13 is secured. This latchplate is of U shape, the side parts being secured to the side parts of the cross-bar and the end of the latch-plate in which the camplate is formed extending across between said side parts. It constitutes, in fact, an inserted or reinforced mouth, within which the movable neck-bar may be inserted and held against swinging or transverse movement. The cam-plate is cut out at its upper edge, forming a cam-opening, the edges of which provide cams 14:. A spring-latch 15 is pivoted in the side parts of the upper cross-bar, as by means of outturned ends 16 passing through holes in the side parts of the upper cross-bar. This spring-latch is formed into a loop adapted to pass over the reduced end 17 of the pivoted neck-bar, the neck-bar being curved or beveled, as shown in Fig. 6, to engage the latch and move it upward as the neck-bar is swung into the bifurcated end of the upper cross-bar. In this upward swinging movement of the latch the side parts engaging the cams 14:- of the camplate are pressed toward each other and put under spring tension. As soon as the neck-bar has passed beyond and into the loop the tendency of the side parts to separate under the spring action causes the latch to snap down over the end of the neck-bar and hold it in place against swinging transverse movement. Appurtenant to the latch-plate is a projection 18, which may be of any desired form and which engages a recess 19 of corresponding form in the pivoted neck-bar and when the parts are engaged locks the latter against downward movement. These interengaging parts cooperate with the latch and latch-plate to securely hold the movable neck-bar and crossbar against separation or relative movement.

The stanchion as a Whole is secured by a flexible connection at the top and bottom, as is usual in devices of this class.

It is obvious that the construction herein illustrated and described may be departed from to a considerable extent and yet embody the invention, and I do not limit myself to the exact construction set out. For instance, the cross-bars need not necessarily be made from a strip of metal. bent to form, (although this is the preferred construction,) but may be formed of any material so long as they are properly secured to the stationary neck-bar and have adjacent to the pivoted neck-bar an opening appurtenant to which is a latch-plate and a reinforeeormouth adapted to receive the neck-bar, and of course it is preferred to provide the cam for tensioning the spring upon this inserted reinforce, having the latchplate, reinforce-mouth, and cam constituting a complete structure, although obviously any form of cam might be used. It is also desirable that in addition to the latch-plate and latch for holding the movable neck-bar against transverse swinging movement there shall be provided appurtenant to the latch-plate and movable neck-bar interengaging parts to securely lock the neck-bar against downward movement With reference to the cross-bar.
